Question

question 23
which of the following is not true of conjugation?
a the donor retains a copy of the transferred genes
b transfers genes for drug resistance
c transfers genes for enzymes and adherence molecules
d involves direct contact between cells
e involves the action of bacteriophage

Explanation:

Conjugation is a bacterial gene transfer process requiring direct cell contact (D is true). The donor retains transferred genes via DNA replication (A is true). It transfers genes like drug resistance (B), enzymes, and adherence molecules (C). Bacteriophages are involved in transduction, not conjugation (E is false).

Answer:

E. Involves the action of bacteriophage
